MapScaler Modifier (World Space)

MapScaler maintains the scale of a map applied to an object. This lets you resize the object without altering the scale of the map. Typically, you might use this to maintain the size of a map regardless of how the geometry is scaled.

• Select an object. > Modify panel > Modifier List > World-Space Modifiers > MapScaler (WSM)
• Default menu: Select an Object > Modifiers menu > UV Coordinates > Map Scaler (WSM)
• Alt menu: Select an Object > Modifiers menu > UVs, Maps and Materials > Map Scaler (WSM)

MapScaler sets the scale of a map on an object.

This differs from the MapScaler (OSM) modifier, which maintains the scale of the map with respect to the object size when scaled with a Select And Scale tool. See the latter's definition for other differences between the two versions.

Note: This world-space modifier is for use primarily with vertically oriented objects, such as walls in an architectural model, or objects with large, flat surfaces. While you can apply the MapScaler to any object, the results are less realistic on curved surfaces, especially complex ones, which can show cracks in the finished texture.

Interface

Scale

Represents the size of one repetition of the texture pattern. Size is measured in current system units. Repetitions occur across the object in the U and V directions. Default=1.0.

Note: When the Use Real-World Texture Coordinates switch is active in the General Preferences dialog, the scale setting defaults to 1.0. If Use Real-World Texture Coordinates is turned off, scale defaults to 100.0.

U/V Offset

Specify horizontal and vertical offsets respectively. Available only when Wrap Texture is off.

Wrap Texture

When on, Map Scaler attempts to wrap the texture evenly around the object. This option requires more computing, but usually produces the most satisfactory results. Default=on.

Wrap Using Smoothing Groups

When turned on, textures are wrapped around corners when they share the same smoothing groups. Curved walls will map smoothly while sharp corners get a new texture origin. This switch is only available when the Wrap Textures switch is turned on. Default=off.

Channel

Specifies the map channel. Default=1.

Up Direction group

• World Z Axis Aligns the map with the Z axis of the world.

  If you choose this option and then rotate the object, the mapping is not fixed to the object.

• Local Z Axis Aligns the map with the local Z axis of the object.

  With this option, the mapping remains fixed to the object.
